SPECIFICATION forming part of Letters Patent No. 296,072, dated April 1,1884. `1 Application filed May 24, 1883., (No model.)

'To @ZZ whom it may concern.:

Be it known that we, THoMAs ISCANTLIN and J AMEs M. ScAN'rLIN, bothcitizens of the United States, residing at Evansville, in the county ofVanderburgand State of Indiana, have invented certainmnew and usefulImprovements in EvaporatorFurnaces, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to those portable evaporators the furnaces ofwhich are mounted on a pair of rockers, in order that either end of theapparatus may be raised or lowered, as occasion may require. Heretoforesuch rockers have been permanently riveted to the sides of the furnace,thereby producingavery heavy and bulky structure, and rendering therockers liable to be bent or broken off in transporting the apparatus.

Our improvement lconsists in-attaching to the furnace-sides suitablesockets or keepers with which the rockers are engaged, but from whichthey can be readily detached after unbolting either one of the endsockets on each side of the furnace, as hereinafter more fullydescribed.

In the annexed drawings, Figures 1 and 2 are elevations showing the twoopposite sides of an evaporator-furnace mounted on our irnprovedrockers. Fig. 3 is a transverse section of said furnace, taken in theplane of the vertical bracesF G. Fig. Lis an elevation of one of saidrockers detached from the furnace.

The furnace A may be of any desired size, shape, and material; but'weprefer to construct it in accordance with the drawings and specicationsof the patent granted to us July 25,

Attached to one side of this furnace, and near the top of the same, arethree sockets or keepers, B B B, supplemented byas many similar devices,C -U C", on the opposite side of said furnace. Of these sets of sockets,the ones B B receive the opposite ends of a rocker, D,while the socketsG C admit the ends of the other rocker, E. The intermediate sockets, BC, receive the upper ends of vertical braces F G, the lower ends of thelatter being securely riveted, respectively, to the rockers D and E;

H H are inclined stays uniting the brace F to the rocker D. I I aresimilar stays connecting the opposite vertical brace, G, with transversebraces, J J', crossing each other under the furnace, as seen in Fig. 3.These transverse bars J J are connected to the vertical rocker E.Furthermore, these central or vcrtical braces, F G, are stiffened with apair of D E are preferably made of angle-iron, so as to combine strengthwith lightness.I As the rocker D, vertical brace F, and inclined staysHH (seen in Fig. 4) constitute a structure that is complete in itself,it is evident said device can be readily applied to the furnace A bysimply inserting the upper end of said brace F in the socket B andslipping one, end of the rocker D into the socket B. The other socket,B, is then applied to the oppositeend of rocker D, and being now boltedto the furnace said rocker is irnmovably clamped in its proper place;but', if desired, the sockets B B maybe fixtures, and the one B bedetached preparatory to the application of the rocker D. It is alsoapparent that the other rocker, E G I 'I, can be as readily secured tothe opposite side of furnaceA by disengaging one of the end sockets C orC, then applying said rocker and brace to the fixed sockets,` andfinally fastening the detached socket to the exposed extrem- Y ity ofrocker E.

The cross-bars J J being now bolted to the vertical bracesF G, thefurnace is at once ready for the application of the evaporating'pan,which latter may be f any approved construction.

lFrom the above description, it is evident the rockers are not retainedin place with rivets keepers, or clip-plates, or bolted directlyto thesides of said furnace. Consequently said rockers can be readily detachedfrom the furnace after removing either of the end sockets B orBGl i1 Byreferring to Figs. 8 and 4, it will IOO concave furnace is such as toadmit the s niokepipe and bars J J in addition to the rockers,

thereby rendering the apparatus self-contained and diminishing thechances of any of `the 5 parts being either broken or lost while beingshipped from place to place.

Inthe drawingsthevarious keepers are represented as screwed or bolted tothe sides of the furnace; but the method of attaching said devices andthe shape of the same may be Varied to suit any special construction ofapparatus.

We claim as our invention- .1. The combinationvithan evaporator-fur- 15nace, of a pair of rockers readily detachable from each other, and alsofrom the furnace,

for the purpose of being stowed within the latter, as herein described.

2. The combination,wth an evaporator-fur- 2o nace, of a, pair of rockersreadily detachable from each other, and also from sockets fastened tothe sides of the furnace, for the purpose of permitting,` said rockersto be stowed within said furnace, as herein described.

3. The combination of furnace A, sockets B 25 B B C C C, rockers D E,and vertical braces F G, said rockers and braces being inserted in saidsockets, substantially as herein described.

4. The combination of furnace A, sockets B B Bl C O C, rockers D E,vertical braces F G, inclined stays HH I 1 and crossed rods J J', whichlatter are attached to said braces F G, substantially as hereindescribed.

In testimony whereof We affix our signatures in presence of twowitnesses. l
